Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings. Those skilled in the art will appreciate that the present invention is not limited to the drawings and the following examples.
In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "far", "near", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and should not be construed as limiting the specific scope of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only to distinguish technical features, have no essential meaning, and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features.
Referring to fig. 1, fig. 1 illustrates the basic structure of a robotic arm as is common in the art. As can be seen in fig. 1, the robotic arm appears to be a human arm lacking a palm and fingers. A particular surgical action needs to be performed by a surgical robotic effector attached to the end of a robotic arm.
Fig. 2 illustrates the structure of a surgical robotic device including a robotic arm, a surgical robotic effector, and a linkage. As can be seen from fig. 2, the end of the mechanical arm 0011 is connected to a surgical robot actuator 0012, the surgical robot actuator 0012 generally includes a circuit, and a mechanical power mechanism and a transmission mechanism connected to the circuit, the circuit structure of the surgical robot actuator 0012 is connected to the circuit of the mechanical arm 0011, and through the circuit connection, the surgical robot actuator 0012 obtains an action command and electric energy for driving the mechanical arm 0012 to perform a surgical action. As shown in fig. 2, the surgical robot actuator 0012 and the mechanical arm 0011 need to be connected into a whole through a connecting member 0013.
Surgical robotic effector 0012 does not perform the procedure directly. In fact, surgical robot actuator 0012 functions as a bridge, which is connected to the surgical robot, receives external commands (e.g., from a surgical control device), and controls and holds a surgical manipulator mounted thereon to perform a surgical operation. By way of example, fig. 3 illustrates the structure of a surgical manipulator. As shown in fig. 3, the manipulator 20X includes a scope body 200 and a scope body 201, the tail end of the scope body 200 is connected to the scope body 201, lumens communicated with each other are arranged in the scope body 200 and the scope body 201, and the scope body 201 is provided with an observation port 2011, an operation channel 2012, a water inlet valve 2013 and a light source inlet 2014. When the surgical manipulator is used for performing surgery, a doctor holds the endoscope body to operate beside the body of a patient, and the body fluid of the patient is easily polluted; secondly, the operation effect is greatly influenced by individual doctors, the accuracy and safety of the operation are difficult to ensure, the standardization and the normalization of the operation cannot be realized, and complications such as bleeding caused by puncturing and damaging adjacent organs or large blood vessels can occur if the experience of the doctors is insufficient.
Referring to fig. 4, an embodiment of the present invention provides a waterproof and lightweight surgical robot actuator, which can connect a mechanical arm of a surgical robot and a surgical manipulator 20X to perform various surgical operations, and thus perform various difficult surgical operations. Because the surgical robot is adopted to assist in carrying out the operation, the problem existing when the doctor holds the surgical manipulator by hand to complete the operation can be well solved. Fig. 4 illustrates a side cross-sectional view of a surgical robotic effector having surgical manipulator 20X installed therein, in accordance with an embodiment of the present invention. As shown in fig. 4, the surgical robot actuator includes a clamping portion 01 and a control portion 02, wherein the clamping portion 01 mainly functions to fixedly mount a surgical manipulator 20X, and ensure that the surgical manipulator 20X does not shake during a surgical procedure; the main function of the control unit 02 is to communicate with an external surgical control device via a cable, obtain a surgical operation command, and drive the surgical manipulator 20X to complete the surgical operation. Surgical manipulator 20X and interface 03 are not part of the surgical robot effector, but are also shown in the figures for clarity of the description of the manner in which the surgical robot operates. The interface 03 has a main function of connecting the robot arm to the surgical robot actuator.
Fig. 5 is a schematic perspective view of a surgical robot actuator according to an embodiment of the present invention. The clamping part 01 mainly comprises a front cushion block 1, a front cover 2, a rear cushion block 3, a rear cover 4, a camera cushion block 7, a cable cover 8, an interconnection piece 9, a lamp strip 10 and a bottom plate 6. The front cushion block 1, the rear cushion block 3 and the camera cushion block 7 are fixedly arranged on the bottom plate 6, and the camera cushion block 7 is a plate with a certain thickness and is used for cushioning a camera arranged above the camera cushion block 7 so as to be convenient for butt joint of the camera and the surgical manipulator 20X; the front cushion block 1 and the rear cushion block 3 are provided with grooves matched with the shape of the surgical operation device 20X on the sides far away from the bottom plate 6, as shown in fig. 5, before the operation, the surgical operation device 20X is clamped into the grooves of the front cushion block 1 and the rear cushion block 3, and the surgical operation device 20X can be basically fixed. For example, the front cushion block 1 and the rear cushion block 3 may be made of plastic, and the size of the groove on the front cushion block 1 and the rear cushion block 3 may be slightly larger than the size of the corresponding portion of the surgical manipulator 20X, so that when the surgical manipulator 20X is engaged with the groove on the front cushion block 1 and the rear cushion block 3, the groove can smoothly clamp the surgical manipulator 20X. It is important to keep the surgical manipulator 20X absolutely fixed during the surgery, and it is not enough to keep the surgical manipulator 20X absolutely fixed only by the engagement of the grooves in the front cushion block 1 and the rear cushion block 3. After the surgical manipulator 20X is snapped into the grooves of the front cushion block 1 and the rear cushion block 3, the front cover 2 and the rear cover 4 provide further fixing and locking. Fig. 6 shows the structure of the front cover 2 and the rear cover 4 in detail, and as can be seen from fig. 6, one side of the front cover 2 and the rear cover 4 is respectively installed on the front cushion block 1 and the rear cushion block 3 through a rotating shaft, and the other side can be respectively locked with the front cushion block 1 and the rear cushion block 3 through a locking mechanism. Before the operation operator 20X is installed, the front cover 2 and the rear cover 4 are set to be in an open state, the operation operator 20X is clamped into the grooves of the front cushion block 1 and the rear cushion block 3, then the front cover 2 and the rear cover 4 are closed, and the locking mechanism is locked, so that the operation operator 20X can be stably fixed and is ensured not to loosen in the whole operation process. The lamp strip 10 may display the operating state of the surgical robot actuator through brightness, a light emitting color, and the like. The base plate 6 is a flat plate, separates the holding portion 01 from the control portion 02, and provides mounting positions for various parts.
Also shown in fig. 5 are the connecting rod 14, the waterproofing membrane 15 and the housing 5, the connecting rod 14, the waterproofing membrane 15 and the housing 5 belonging to the control section 02. The link 14 mainly functions to output power of the control portion 02 to the surgical manipulator 20X, and the waterproof film 15 prevents liquid (e.g., irrigation liquid during surgery) in the grip portion 01 from leaking into the control portion 02. The casing 5 separates the inside of the control portion 02 from the outside.
The specific structure of the interface 03 is also shown in fig. 5. The interface 03 mainly comprises an interconnection cover 11, a threaded sleeve 12 and a threaded disc 13, and the function of the interface 03 is to connect the surgical robot actuator with the robotic arm, and since the interface 03 is not part of the surgical robot actuator, it will not be described in detail herein.
Fig. 7 shows the internal structure of the surgical robot actuator control section 02. As shown in fig. 7, the control portion 02 mainly includes a connecting rod 14, a waterproof film 15, a front bearing seat 16, a lead screw 17, a linear bearing 18, a slider 19, a lead screw nut 20, a limiting ring 21, a photoelectric sensor 22, a rear bearing seat 23, a coupling 24, a motor support seat 25, a servo motor 26, an optical axis 27, and a housing 5. In the operation process, the servo motor 26 drives the screw 17 to rotate, the screw nut 20 drives the sliding block 19 to do reciprocating linear motion, and the connecting rod 14 arranged on the sliding block 19 is connected with the operation manipulator 20X, so that the servo motor 26 drives the operation manipulator 20X to do front and back telescopic motion.
As previously mentioned, one of the improvements of the present invention over the prior art is the addition of an overall waterproof structure. These waterproof structures will be described in detail below. Fig. 8 is a side view of a surgical robotic effector in accordance with an embodiment of the present invention. Fig. 8 shows the waterproof membrane 15 described above, and the drain hole 28 provided in the housing 5. The link 14 transmits power to the surgical manipulator 20X, for which the link 14 needs to move back and forth in the direction along the surgical manipulator 20X, and an elongated opening (which is covered by a waterproof film, not visible in the drawings) that allows the link 14 to move back and forth is provided on the base plate 6. During the operation, the wound of the patient may bleed, and a large amount of the washing solution (generally, physiological saline) is required for the washing, so that the washing solution inevitably leaks into the holding portion 01 during the operation. If the rinse solution enters the underlying control portion 02 from the elongated opening, it may corrode components in the control portion 02, resulting in damage to the apparatus. In order to prevent the washing liquid from leaking into the control portion 02, a waterproof film 15 is provided to cover the elongated opening. As shown in fig. 8, the waterproof membrane 15 is like an inverted funnel, with the lower portion closely attached to the surface of the bottom plate 6 and the upper portion closely attached to the outer surface of the connecting rod 14. The waterproof film 15 is made of an elastic material, such as a rubber film, and when the link 14 moves, the elastic film 15 deforms along with the movement of the link 14, and always keeps close adhesion to the link 14 and the bottom plate 6, thereby preventing the washing liquid from entering the control portion 02 from the holding portion 01 through the elongated opening. In an extreme case, for example, when the elastic membrane 15 is broken and the rinse liquid enters the control portion 02, the plurality of drain holes 28 are provided just below the housing 5 facing the elastic membrane 15, and the rinse liquid also leaks from the drain holes 28. Since the parts requiring the most waterproofing are separated by the rear bearing block 23, the servo motor 26 is located in another compartment (see fig. 7), so that the core parts of the control portion 02 are not affected.
As shown in fig. 9, in order to fix the base plate 6, a screw hole 29 is usually provided at an appropriate position on the base plate 6, and the base plate 6 is fixed to the interface 03 or the front bearing housing 16 and the rear bearing housing 23 by screws. These threaded holes 29 cannot be completely closed by screws, and if there is flushing liquid on the base plate 6, this flushing liquid or water vapor can pass through the gaps of the threaded holes 29 into the underlying control part 02 with caution. To solve this problem, a waterproof pad is provided above the screw hole 29. For example, the waterproof pad may be a rubber pad.
Fig. 10 illustrates a view of the lower frame of the surgical robotic effector, the lower frame including the housing 5, the housing 5 including the housing channel 30 and the front and rear bearing mount mounting slots 31. Rubber rings are arranged in the shell groove 30 and the front and rear bearing seat mounting grooves 31, so that all spaces in the surgical robot actuator are isolated from each other, and even if water vapor or liquid water appears in a certain cabin, other cabins cannot be influenced.
Fig. 11 shows an enlarged view of the interface position structure of the surgical robot effector, including the joint 32 of the interface 03 and the surgical robot effector. A waterproof rubber ring is provided at the joint 32 to prevent the flushing fluid or water vapor inside the surgical robot actuator from entering the robot arm through the interface 03.
In order to reduce the weight of the surgical robot actuator and make the surgical robot actuator more portable and portable, the non-stressed part of the surgical robot actuator is made of plastic (such as nylon). The non-stressed components comprise a shell 5, a front cushion block 1, a front cover closing 2, a rear cushion block 3, a rear cover closing 4, a camera cushion block 7, a cable cover 8, a lamp strip 10, a linear bearing 18 and the like.
In the development process, the inventor of the present invention also noticed that the existing surgical robot actuator has a large noise in the operation process, and the noise source mainly comes from the moving components made of metal materials, such as the optical axis, the lead screw, the bearing, etc. In order to reduce noise, the inventors of the present invention have manufactured bearings, linear bearings, and screw nuts among the above-described components by using a non-metallic material (e.g., a polymer material). After the improvement, the noise generated by the surgical robot executor in the surgical process is reduced by more than 50%.
Fig. 12 is a schematic structural diagram of a surgical robot system according to an embodiment of the present invention. As shown in fig. 12, the surgical robot system includes: a surgical robotic device 001, a surgical monitoring device 002, and a surgical control device 003.
The surgical robot 001 is connected to a surgical control device 003, and performs a puncture operation (for example, percutaneous renal puncture) according to a puncture path, a channel expansion, and a lithotripsy operation in accordance with a surgical control command transmitted from the surgical control device 003.
The operation monitoring device 002 is connected to the operation control device 003, scans the current operation implementation position in real time during an operation, sends the acquired scan data of the current operation implementation position to the operation control device 003, and displays the scan data in the form of an image to an operator (e.g., a doctor).
The operation control device 003 acquires operation site (for example, kidney) scanning data from an external scanning device, and establishes a three-dimensional model of a lesion site (for example, kidney and stone) according to the operation site scanning data; according to the matching result of the three-dimensional model and the preset model, a puncture path is determined, navigation information is determined according to the puncture path and the scanning data, a surgical control instruction is generated according to the navigation information and sent to the surgical robot device 001, and the surgical operation is executed by the surgical robot device 001.
Before the operation is performed, the lesion (for example, kidney) of the patient is scanned by the external scanning device, and then the scanning data obtained by the scanning of the external scanning device is acquired by the operation control device 003, so as to establish a three-dimensional model of the lesion (for example, kidney and stone) of the patient. For example, the surgical control apparatus 003 may be a computer device and is installed with software for creating a three-dimensional model based on scan data, and the external scanning apparatus may be at least one of a magnetic resonance examination apparatus, an electronic computed tomography apparatus, and an ultrasound scanning apparatus. After the three-dimensional model is established, the three-dimensional model can be displayed to a doctor through a display connected with the operation control device 003 so that the doctor can determine an operation scheme according to the three-dimensional model, operation planning and simulation pre-puncture verification are performed through computer software, a puncture path for performing an operation on a patient is input through input equipment (such as a mouse and a keyboard) configured in the operation control device 003, and software can be formulated through the operation scheme installed in the operation control device 003 so that the puncture path is determined according to the three-dimensional model and a pre-stored operation model. Thereafter, the physician is required to confirm the software-derived protocol, or modify the software-derived protocol. The surgical control device 003 determines navigation information for performing puncture or lithotripsy based on the set puncture path and the scan data transmitted from the surgical monitoring device 002, and transmits a surgical control command to the surgical robot device 001, and the surgical device provided in the surgical robot device 001 performs surgery. For example, the surgical robot apparatus 001 includes a waterproof and lightweight surgical robot actuator according to an embodiment of the present invention.
